Abstract
A computing method of the mooring force of buoy mooring system under the joint action of wind, wave and current was developed in time domain. Nonlinear five-order Strokes and design-wave method were adopted for wave load analysis and the flow load and wind load on vessel were acquired by empirical formulas. With initial conditions derived from quasi-static method, the time history of vessel and mooring force were obtained without considering the impact of dynamic effect of chain and buoy on the vessel motions. Then, 2-D plumped mass method was employed to form the mathematical model of chain and buoy, the dynamic equations of which were obtained by Houbolt method, and the mooring force were also corrected. The computational results were in good agreement with those by other experimental formulas and thus proved that the method established in this paper can be used for computing the mooring force of buoy mooring system.
